Title
Noncrystalline blue-emitting 9,10-diphenylanthracene end-capped with triphenylamine-substituted fluorene
Abstract

Two blue-emitting oligomers, namely FDPA1 and FDPA2 containing 9,10-diphenylanthracene core end-capped with triphenylamine-substituted fluorene has been synthesized and characterized. The spiro-configuration end-capping groups imparts two compounds with pronounced morphological stability (Tg > 185 °C, Td > 420 °C) and excellent hole injection ability (EHOMO > −5.27 eV) with the advantageous optical characteristics of corresponding core. Scanning electron microscope (SEM) and X-ray diffraction (XRD) reveal that the two oligomers form excellent amorphous films and possess good morphological stability after annealing.

► Novel nonplanar oligomers containing DPA core were facilely prepared. ► Possessing good thermal and morphological stabilities. ► Maintaining the high fluorescence quantum yield and wide energy gap of the DPA core. ► Excellent hole-injection and -transporting ability of the resulting materials.
